Abstract

L'invention concerne un dispositif (10) permettant de fixer des éléments d'étanchéité (12, 14) dans un évidement (16), notamment dans une gorge de montage façonnée dans une turbomachine, comprenant au moins un élément porteur d'étanchéité (18) comportant au moins un élément d'étanchéité (12, 14). Au moins un corps de fixation (20) est disposé entre l'élément porteur d'étanchéité (18) et un corps de serrage (22) associé à l'élément porteur d'étanchéité (18), le corps de fixation (20) étant relié de manière à former une partie intégrante avec l'élément porteur d'étanchéité (18) et le corps de serrage (22) au moyen d'éléments de liaison (24) en forme de languettes libérables à force. L'invention concerne également un procédé de fixation et un procédé de fabrication du dispositif (10) selon l'invention.
